Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy production technology, and specifically to a stamping and forming equipment for aluminum alloy production. Background Technology

[0002] Stamping is a forming method that uses a press and dies to apply external force to sheet metal, strip, tube, and profiles, causing plastic deformation or separation to obtain workpieces (stamped parts) of the desired shape and size. The blanks for stamping are mainly hot-rolled and cold-rolled steel sheets and strips. In the aluminum alloy production process, to form the aluminum alloy into the required shape, stamping is mostly performed using forming equipment and corresponding dies. The existing technology has the following problems:

[0003] Chinese patent document CN221559617U discloses a stamping forming equipment for aluminum alloy production. The technical solution includes: a machine box with through-beams on both sides; a support box with through-beams on both sides is fixedly installed inside the machine box; a support plate is slidably connected inside the support box; a support rod is fixedly connected to the top surface of the support plate; a template is fixedly connected to the top of the support rod; openings are symmetrically opened on both sides of the support box; a fixed shaft is fixedly connected inside the opening; a wedge block is rotatably connected to the fixed shaft; the wedge block extends into the interior of the support box. The beneficial effect of this invention is: by setting the wedge block and the abutment plate, when the upper template moves upward, the die contacts the inclined surface at the bottom of the wedge block; the abutment plate blocks the wedge block, thereby limiting the wedge block and preventing it from blocking the die. The upper template continues to move, causing the die to detach from the upper template.

[0004] Although the aforementioned literature can automatically separate the mold and the upper mold plate, the fixed size of the support box means that the fixed-position wedge block cannot be effectively demolded when stamping different molds, resulting in the low applicability of the overall stamping equipment.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figure 1, Figure 2 , Figure 3 As shown, this utility model provides a stamping forming equipment for aluminum alloy production, including a stamping platform 1. A lower template 2 is fixedly installed on the top of the stamping platform 1. A lower die 3 is set on the top of the lower template 2. A pressing mechanism 4 is set above the lower die 3. Four guide slide rods 11 are fixedly installed in a rectangular array on the top of the lower template 2. A top plate is fixedly installed on the top of the four guide slide rods 11. A hydraulic cylinder 12 is fixedly installed on the top of the top plate. The pressing mechanism 4 includes an upper template 41. The output end of the hydraulic cylinder 12 extends through to the bottom of the top plate and is fixedly connected to the top of the upper template 41. The upper template 41 is slidably connected to the four guide slide rods 11. Two T-shaped grooves 42 are opened on both the left and right sides of the upper template 41. The bottom of the upper template 41 is provided with... An upper mold 43 is provided, which is fixedly installed below the upper template 41 by means of a T-slot 42. The upper mold 43 is located directly above the lower mold 3. Demolding mechanisms 44 are provided on both the front and rear sides of the upper mold 43. An adjustment slide 411 is provided at the bottom of the upper template 41. A positive and negative threaded rod 412 is movably installed on the rear side of the inner wall of the adjustment slide 411. The front end of the positive and negative threaded rod 412 extends through to the front side of the upper template 41 and is fixedly installed with a rotating handle 413. The front and rear sides of the outer wall of the positive and negative threaded rod 412 are respectively provided with threaded walls with opposite threads, and the outer walls of the two threaded walls are threaded with adjustment and moving hanging plates 414. The left and right sides of the two adjustment and moving hanging plates 414 overlap with the left and right sides of the inner wall of the adjustment slide 411, respectively.

[0024] In use, the matching lower mold 3 and upper mold 43 can be installed at the bottom of the lower template 2 and upper template 41, and fixed by the T-slot 42. Then, according to the front and rear width of the upper mold 43, the rotating handle 413 on the front side of the upper template 41 can be rotated, thereby driving the positive and negative threaded rods 412 in the adjusting slide 411 to rotate. By using the threaded walls of the opposite threads on the front and rear sides of the outer wall of the positive and negative threaded rods 412 to connect with the threaded adjustment and moving hanging plate 414, the two demolding mechanisms 44 can be controlled to move closer to the front and rear sides of the upper mold 43, thus adapting to upper molds 43 of different sizes. During stamping, the lower pressing mechanism 4 is driven to descend as a whole by the hydraulic cylinder 12. The guide slide 11 ensures the stability of the descent of the lower pressing mechanism 4. Finally, the upper mold 43 and the lower mold 3 are combined to complete the stamping of the aluminum alloy material in the lower mold 3.

[0025] like Figure 4As shown, both demolding mechanisms 44 include a demolding control box 441. The bottom ends of the two adjustable movable hanging plates 414 are fixedly connected to the top of the two demolding control boxes 441 respectively. The bottom left and right sides of the two demolding control boxes 441 are provided with slide grooves 442, and slide rods 443 are fixedly installed between the front and rear sides of the inner wall of the slide grooves 442. The outer walls of the two slide rods 443 included in the two demolding control boxes 441 are slidably installed with U-shaped extrusion plates 445. A compression spring 444 is fixedly installed on the side of the U-shaped extrusion plate 445 away from the upper mold 43. The compression spring 444 is located on the outside of the slide rod 443. An inclined extrusion plate 446 is provided at the bottom of the horizontal position of the two U-shaped extrusion plates 445.

[0026] When the upper mold 43 descends, it also causes the demolding control box 441 to descend as a whole. Since the two inclined extrusion plates 446 extend to the bottom of the upper mold 43 at opposite ends and are inclined, when the upper mold 43 and the lower mold 3 are combined, the upper mold 43 will first extrude the top inclined surface of the inclined extrusion plates 446, thereby causing the two inclined extrusion plates 446 to move in opposite directions to the front and back sides, and causing the U-shaped extrusion plate 445 to move by sliding on the outer wall of the slide rod 443 in the slide groove 442. At the same time, the compression spring 444 is compressed. When the upper mold 43 finishes stamping and rises, the inclined extrusion plates 446 will use the compression spring 444 to spring back and extrude the U-shaped extrusion plate 445 to reset. The two inclined extrusion plates 446 will use the opposite ends to extrude the aluminum alloy mold stuck at the bottom of the upper mold 43 at an angle downward, thereby causing it to fall off and completing the demolding.

[0027] like Figure 5 As shown, an adjusting threaded rod 4451 is movably installed at the bottom of the horizontal position of each of the two U-shaped extrusion plates 445. Each of the two inclined extrusion plates 446 has a threaded hole 4461 that runs vertically through it. The inclined extrusion plates 446 are threadedly connected to the adjusting threaded rod 4451 through the threaded hole 4461. A knob 4452 is fixedly installed at the bottom of the adjusting threaded rod 4451. A limiting slide rod 4453 is fixedly installed on the left side of the bottom of the horizontal position of the U-shaped extrusion plate 445. The inclined extrusion plate 446 is slidably connected to the limiting slide rod 4453.

[0028] Depending on the thickness of the upper mold 43, the adjusting threaded rod 4451 can be rotated by rotating the knob 4452. With the threaded connection between the threaded hole 4461 and the adjusting threaded rod 4451, the inclined extrusion plate 446 can be controlled to slide stably down on the outer wall of the limiting slide bar 4453, thereby adapting to thicker upper molds 43 for demolding.

[0029] The working principle of this stamping and forming equipment for aluminum alloy production will be explained in detail below.

[0030] like Figure 1-5As shown, during use, the matching lower mold 3 and upper mold 43 can be installed at the bottom of the lower template 2 and upper template 41, and fixed using the T-slot 42. Then, according to the front and rear width of the upper mold 43, the rotating handle 413 on the front side of the upper template 41 can be rotated, thereby driving the positive and negative threaded rods 412 in the adjusting slide 411 to rotate. By using the threaded walls of the opposite threads on the front and rear sides of the outer wall of the positive and negative threaded rods 412 to connect with the threaded adjustment and moving hanging plate 414, the two demolding mechanisms 44 can be controlled to move closer to the front and rear sides of the upper mold 43, thus adapting to upper molds 43 of different sizes. During stamping, the hydraulic cylinder 12 drives the pressing mechanism 4 to descend as a whole, and the guide slide 11 ensures the stability of the descending pressing mechanism 4. Finally, the upper mold 43 and the lower mold 3 are combined to complete the stamping of the aluminum alloy material in the lower mold 3. At the same time, when the upper mold 43 descends, it also drives the demolding control box 441 to descend as a whole. Since the two inclined extrusion plates 446 extend to the bottom of the upper mold 43 at opposite ends and are inclined, the upper mold When the upper mold 43 merges with the lower mold 3, the upper mold 43 will first press the top inclined surface of the inclined extrusion plate 446, thereby causing the two inclined extrusion plates 446 to move in opposite directions to the front and rear sides, and driving the U-shaped extrusion plate 445 to move by sliding on the outer wall of the two vertical sliding rods 443 in the slide groove 442, while compressing the compression spring 444. When the upper mold 43 completes the stamping and rises, the inclined extrusion plate 446 will use the compression spring 444 to spring back and press the U-shaped extrusion plate 445 to reset. Two inclined extrusion plates 446 press the aluminum alloy mold stuck at the bottom of the upper mold 43 downwards at opposite ends, thereby causing it to fall off and complete the demolding. At the same time, depending on the thickness of the upper mold 43, the adjusting threaded rod 4451 can be rotated by rotating the knob 4452. With the inclined extrusion plates 446 connected by the threaded hole 4461 and the adjusting threaded rod 4451, the inclined extrusion plates 446 can be controlled to slide stably down on the outer wall of the limiting slide rod 4453, thus adapting to thicker upper molds 43 for demolding.

[0031] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
